I have recently acquired an iMac 333 and it was running OS 9.1 so I figured it's a G3 lets get it right bang up to date and install 9.2.2, which I did.
To cut a long story short I went to adjust the sound control panel the other day, the message I got was this:-

The application "Sound" has unexpectedly quit, because an update to this software is required for compatibility with the improved Mac OS file system.

You should save work and restart etc...

Not what I was expecting. I have looked at the apple updates site (nothing new about sound control panel) and run software update, but the message still appears. Sound control panel version is 8.5.6

Any ideas or thoughts will be greatly appreciated.
